HEATING sYsTniu.

To all whom .'i't-mayiconcem:

`Be it known that I, EGBERT H. GOLD, a

the United States,`

Chicago, in the county of Cook and State of .Illinois,haveinventedcertain new and useful Improvements in Heating Systems, of

- which the following is aspecication.

My inventionvrelat'es to. heating systems particularlyadapted forheatingv railway cars, and `has for its object lto provide a heatingsystem employing several radiating coils or radiators which may becontrolled by a. single automatic controller, if lsuch controller beused, which coils are provided with switching` devices, lwhereby certainof the coils may-be put into service singly, when desired, o r inconjunction with other coils,

one or more of these other `coils being of a strictly vsecondary orsupplemental character, that is, receiving steam` only when the.firstinentioned orprimary coils are in service.

While the arrangement of radiators, valves and controlling devices whichforms the subject-matter of this application might be employed'invariousheating systems' of diifer` ent description, this arrangementisparticulai-ly' designed and intendedfor an atmospheric. pressure orvapor system of heating and, more especially,;' for a vapor system whenused to heata sleeping car or the like, and in this regard it is one ofthe objects of my invention to adapt and modify the wellknownivaporsystem of car heating to meet certain requirements of sleeping cars.

In my application Serial No. 500,477, filed June 7, 1909, I have showntwo coils, a main coil and a supplemental coil, controlled by a singleVautomatic controlling device and provided with valves whereby steam maybe circulated through the main coil or through themaincoil andthesupplemental coil in succession; and in my application Serial No.

500,478, filed June 7, 1909, I have shown and claimed a parallelarrangement of coils,

Aalso controlled by a single controller, in

which the several coils are capable of being supplied with steamindependently, but

which coils may be so connected as to receive the `steam serially incombination with certain other devices and arranged so as to provide asuitable system for heating apartment cars. The present invention combines the arrangements of the two aforementioned applications, therebyproviding'an ,arrangement ofthree coils, all of which may be conresidingat same principles.

.trolled by a single automatic controller, two of Whichcan be usedindependently of4 each other and of the third, the third being a sec-vondary ior supplemental coil which is fed from and dischar es linto oneof the rstmentioned coils. bviously, the coils might be multiplied toany desired extent upon the The arrangement is preferably such that thesteam, of necessity, flows in series through such of the coils as aredanger of short open coi s. v

The invention is illustrated as applied to heatingl a sleeping cardivided into a main seating section and a compartment, for eX ample, thewomens lavatory; and it is one of the objects of my invention to providea heating system which shall adequately meet the exigencies of this andsimilar situations. The invention might, how.-

eVer, be employed in other connections.

The invention has for further objects such other new and improvedconstructions, devices and arrangements in heating systems as will bedescribed in this specification and particularly set forth in the claimsappended hereto.

The invention in the preferred embodiment is. illustrated in theaccompanying drawings, wherein- Figure l 'is a fragmentary, sectionalplan construction,

however, diagrammatic for the purpose of clearness of illustration. Fig.2 is a sectional.. plan view through the three related four-Way valvesand their connecting pipes. Fig. 3 is a section taken on line 3-3 ofFig. 2, looking in the form of vapor regulator suitable for use in thisconnection.- l

vLike characters of reference indicate like parts in the severalfiguresof the drawings.

Referring to thedrawings, reference letter A designates a sleepin@ carof ordinary construction divided into tlie seating section Band a.compartment C, the latter forming the Womens lavatory.

Reference letter a designates the seats. D is the train pipe, which runsthe length of the train and is kept filled with steam from thelocomotive at 'relatively high but variable pressures.

direction of the arrows;. 'and Fig. et is a vertical, sectional view ofa y preferably provide a main radiating coil E, which runs thelength ofthe car, through' the seating portion B and also t-he lavatory C,beingarranged adjacent to the water pipes and the like, so as to keepthe latter from freezing. This coil is shown in horizontal position in Fig.l 1, in order that all of the devices constituting the heating fsystem may be clearly shown in a single lorview. In practice, thesepipes will be ara ranged in the customary place along the ysides of thecar. The radiator E is calcu- Ylated toafford suiiicient radiatingsurface to -keep the'car' orthe lside of the car on' which it is locatedheated to a normal temperature in moderate weather and to impartsuicient heat toprevent the water pipes in the car from `freezing up inany weather.

' This radiator is intended to be kept in service 20 all the time, dayand night, in winter time, While thefcar is in service. For supplyingadditional heat to the seating section of the car, incase of coldweather, and particularly in the day time, I provide a supplemental 25,lcoil Fwhich is so connected withthe main coll E that itreceives steamonly when the' main coil is in service. For heating' the womenslavatory, I provide an additional.

coil G, which is so'connected with the other f coils that it may be putunder steam in conjunction with the main coils E, F or independently ofthe same. n

H re resents the vapor regulator, by

means of which steam is'maintained at sub` stantiallyatmosphericpressure in such of the coils as may be in service; and J, J J 2'fpur-way valves interposed between the radiators and the controller inthe manner which will be hereafter described. v

A suitable form of vapor regulator is shownin-Fig. 4, although any otherdevice might be employed for controlling the inflow to the radiatingpipes in accordance r with thermostatic conditions adjacent their v...45 common outlet. A casing 10 is divided by a partition-11, so as toform a' high' pressure chamber 12j and a low pressure chamber 13, thesechambers being in communication by means of a port 14 closed by a valve15 arranged on a stem 16, which is pivoted to a bell crank 17. Arrangedin a thermostat chamber 18 is a thermostat 19 upon which.'

- rests a rod 20, pivoted to the other end 'of V bell crank 17 Figs. 2and 3 show the construction and arrangement of the four-way valves.These valves are identical in construction, so that A but one needs tobe described. A casing 21 is divided by webs 22, 23, 24, 25 into com`*50 partments, 26, 27, 28 and 29. Between the webs is arranged avalve-piece consisting of the upper disk 30 and the lower disk 31,connected lby a vertical web 32. These parts 'are arranged on a stem 33provided with a 'handle 34, a spring 3'5 being interposed be- J and -26of J2.

.womens lavatory tween the bonnet 36 and the upper disk 30. The lowerdisk is perforated at 37, which perforation registers with a perforation38 in the bottom of the casing when the web 32 "isin the dotted lineposition of Fig. 2.

- A short pipe section 39 connects the train `pipewith the high pressurechamber 12.

T he low pressure-chamber 13 is connected by pipe 40 with compartment 26of valve J. Compartments 27 of valve J and 26 of valve J are connectedby a pipe 41. A pipe 42 leads from .compartment 27 of J to thethermostat chamber 18 of thermostat H. A short pip'e43 connectscompartments 28 of 4 kThe inlet and return ends 44 and 45'of` coil Grlead respectively from and to compartments 29 and 28 of valve J.

The inlet and return ends 46 and 47 'of coil E lead vrespectively fromand to compartments 29 of J and 27 of J2. Theinlet and return ends 48and 49 of coil F lead respectiyely from and to compartments 28 and' 29 oJ2.

The operation of the heating system when constructed as above describedis as follows: Coil E will be kept filled with steam at atmosphericpressure whenever the car is inservice and requires heat. In moderateweather this coil will 'suffice to heat the car even in the day time.During' the sleeping hours, itwill be used alone, even in quite coldweather. It isa source of complaint that, as sleeping cars are nowheated, the temperature is too high during the night and particularlyduring the iirst hours of the night. vThis results from that fact thatvthere is no way of putting out of service a part of the heating coils. Iobviate this ob?, jection by dividing the radiator into subdivisionswhich'c'an be used' separately or and 27 of valve J, compartment 26 ofvalve J to coil E and from coil E through compartments 27 and26 of valveJ2, compartments 28 and 27 of valve J and-thence through pipe 42 to thethermostat chamber 18 of the controller. Valves J and J 2,will be set inthe position shown by the dotted lines In cold weather,

inv Fig. 2, short circuitin coils Gr and F. By

shifting the position o the valve-piece of J2, the steam, after passingthrough coil E, Will be forced to pass through coil F before it canreach the thermostat chamber. Coil gemaa- G may be cut into the circuitby shifting the valve-piece'ot valve J to the positionv shown oftheradiators as may be in service;l The'- jsteam vo long astliesame is4open, and then goes Ward reaches the thermostat chamber 18 by ineans'ofthe common discharge pipe 42 leading from valve J.: The Contact of thevsteam With the thermostat expands, the same,-

causing port 14 to be either closed entirely or throttled. As ya result,only so 'much so arranged as to protect the water pipes,

sie

steam passes'valve l5 as will suiHce for keeping the radiating coils inservice' fullof steam at substantially atmospheric pressure. It willbenoted that the supplemental radiator F, that is the supplemental coilwhich' runs, through' the berth section of the car, can not by anypossible manipulation be used alone, therefore it is impossible 'forail-ignorant or careless porter. to heat-the berth section of the carwithout employing the main or long coil Eivhich is preferably drips,basins, etc., which Would be likely to become frozenup'A in very coldWeather. On the other hand, the supplemental coil Gr can be'usedindependently of the main coil E, this being necessary when, forexample,

,the supplemental coil. G is employed for heatinga Womans lavatory whichmay requir heat very early in themo'rning even .When no heat is neededin the berth section.

I do notlimit'inyself to the particular deyices, constructions andarrangements shown and described, as inodiiications might be devisedWhich would come Within'the scope of iny invention as defined by theclaims. p

Following the customary practice, the heating described for oneside of acar will ordinaril e duplicated on the other side I dol ot claimspecically in this specification'fithe parallel arrangement of the four-Way valves J, J and their respective coils G and E, nor do I claimspecifically the serial arrangement 'of the .valves J J2 and theirrespective coils E and F, as similar arrangements are shown and claimedin my co-pending application, Serial No. 500,477,
